Attribute data_nonce, data_action, data_postid not allowed errors

我正在检查w3c验证器上的代码，我不断得到这些错误的每个个人博客和投资组合的帖子，有"喜欢"按钮附加到它。我能做些什么来纠正这些错误，使它们正确验证吗?

下面是一个示例代码:

<a href="#" class="like " title="Like this" data_action="likepost" data_postid="74" data_nonce="13e20f93ee">
    <span class="glyphicon glyphicon-heart"></span>
    <span class="likecount">2</span>
</a>

确保你有这样的doctype声明:

<!DOCTYPE html>

并将自定义属性替换为:

data-action data-postid and so on.

注意hyphen而不是underscore。HTML5允许自定义属性，建议使用以data-开头的属性。

A custom data attribute is an attribute in no namespace whose name starts with the string data-, has at least one character after the hyphen, is XML-compatible, and contains no uppercase ASCII letters
